This also add supports for 4K DeckLink cards because they always output the
ancillary data in 10-bit.
v2:
- only try teletext decoding for 576i PAL mode
- some comments as requested by Aaron Levinson

This one changes the previous vmaf patch to libvmaf to keep it separate from the
native implementation of vmaf inside ffmpeg later.

The pkg-config file is relatively new (2013), so some distros might
not have it yet. And the -lstdc++ being required for the static lib
is only present since the last release in December 2016.

Add the debug_threads boolean field to PerThreadContext. For
PerThreadContext *p, p->debug_threads records whether the
FF_DEBUG_THREADS bit is set in p->avctx->debug, and p->debug_threads and
p->avctx->debug are kept in sync. The debug_threads field is defined as
an atomic_int to allow atomic read by another thread in
ff_thread_await_progress().
This fixes the tsan warning that

The only use of that argument was for Opus downmixing which is very rare

It is redundant with costable. The first half of sintable is
identical with the second half of costable. The second half
of sintable is negative value of the first half of sintable.
The computation is changed to handle sign of sin values, in
C code and ARM assembly code.

This mode apparently does not support decoding of HEVC Main (8 bit).
With D3D11 and Intel drivers on Windows 10 I get green corruption, while
using DXVA2_ModeHEVC_VLD_Main works.
In url_find_protocol(), proto_str is either "file" or a string
consisting of only the characters in URL_SCHEME_CHARS, which does not
include ','. Therefore the strchr(proto_str, ',') call always returns
NULL.
Note: The code was added in commit
6161c41817.

When 'out' is an AVFrame that does not have buffers preallocated,
swr_convert_frame tries to allocate buffers of the right size. However
in calculating this size it failed to check for whether 'in' is NULL
(requesting that swr's internal buffers are to be flushed).
